IMPROVEMENT IN CULTIVATORS.

Specification forming partof Letters Patent No. 221,289.

dated November 4, 1879; application filed July 8, 1879.

To all whom it may concern:

Be it known that I, JONAS DIERDORFF, of Goshen, in the county of Elkhartand State of Indiana, have invented a new and useful Improvement inCultivators, of which the following is a specification.

Figure 1 is a side view of my improved device. Fig. 2 is a top view ofthe same.

The object of this invention is to furnish an improved attachment forcultivators, the use of which will avoid the use of stay rods or chains,will give a direct draft, and will prevent any down-draft upon thehorses necks, and which, at the same time, shall be simple inconstruction and convenient in use.

The invention consists in the combination of the two hinged bars,provided at their rear ends with clevises or loops and clevis-holes,

the coupling-block having its forward end slotted to receive the doubletree, and the long screw or brace, provided with the two with eachother, to adapt the device to be applied to a cultivator, as hereinafterfull y described.

Similar letters of reference indicate corresponding parts.

A represents two bars, to the. rear ends of which are attached clevisesor clips a, to connect the said ends with the lower parts of the arms ofthe bow or arch of the axle. In the rear ends of the bars A are formedholes to receive the clevises for connecting the plow-beams or axle of acultivator with the said ends. The forward ends of the bars A are hingedto the rear end of the draft-block B by bolts, the said rear end beingrabbeted upon the upper side to receive the forward ends of the saidbars. The forward end of the coupling or draft block B is slotted toreceive the double-tree, which is pivoted to it by a bolt. 'To themiddle part of the coupling-block B is attached the lower end of a longscrew or brace, G, which is designed to pass up through the tongue ofthe cultivator in the place where the double-tree is usually pivoted,where it is secured in place by two nuts, 0, screwed upon it above andbelow the said tongue.

With this construction, by nuts 0 upon the screw 0 the and with it thedoubletree, may be raised and lowered, as the height of the plants mayrequire.

- Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination, in a cultivator with anarched axle and tongue, of the draft-block B, the bars AA, hingedthereto in front, and provided with the side loops or clips, a, at theother end, and the screw 0, having nuts 0, as shown and described,whereby the bars A and block B may be elevated or depressed, to suit theheight of the growing crop, without affecting the depth or position ofthe plows.
